查询词典 sulfur black

The needed potential for the oxidative dissolving of chalcocite increases gradually with the decrease of Cu/S ratio in this mineral during leaching of chalcocite. When chalcocite changes fully into covellite the needed potential for leaching to produce element sulfur and Cu〓 maintains unchangeable.

The noxious gas contained in the tail gas out of garbage incinerator and coal burning boiler is collected by bag filter with japanese techniques, This technology can achieve desulfuration and harmness gas through ejecting slaked lime dry power and reaction auxiliary agent to fult gas, sulfur dioxide and harmful gas.harmful gas and slake lime carry chemical reaction adequately,forming solidastate calcium sulfate and and other attachments, which will either adhere to stive or coacervate into nice granule and finally been absorbed.

垃圾焚烧炉尾气中的有害物质和燃煤锅炉煤中的硫燃烧后主要是以二氧化硫的形态存在，这种呈气态的二氧化硫和有害气体是无法用任何其它种类除尘器收集和捕捉的。本技术是通过向含有粉尘、二氧化硫和有害气体的烟气中喷射熟石灰干粉和反应助剂来实现脱硫、脱有害气体的。二氧化硫、及有害气体和熟石灰在反应助剂的辅助下充分发生化学反应，形成固态硫酸钙(CaSO4)和其它附着物，附着在粉尘上或凝聚成细微颗粒，随粉尘一起被袋式除尘器收集下来。
